摘要 A ternary co polysilane was synthesized by the Wurtz type coupling reaction and characterized by FI IR , XRD, TEM, UV and fluorescence spectroscopy. The results show the copolysilane is amorphous and partly ordered in structure. The TEM image indicates the copolysilane possesses a rodlike structure. It decomposes at temperature near 300 ℃, has a better thermal stability than polymers with —C—C— main chain. The UV spectrum of the copolysilane displays a strong and broad absorption range. It emits strong fluorescence at 420 nm and could be a kind of promising photoluminescence material.
